This Chicken and Green Bean Casserole is an easy weeknight meal packed with cheesy chicken in a creamy sauce. The crunchy French-fried onions on top add the perfect finishing touch.

One of my holiday side dishes is green bean casserole. It competes only with sweet potato casserole and buttery rolls. I love that vegetable casserole so much that I even use the leftovers to make green bean casserole pizza!
If you love this easy side dish too, why not turn it into a main dish by adding protein? This easy chicken and green bean casserole recipe has the comforting flavors of the holidays with the ease of a weeknight dinner.
Ingredients in Chicken and Green Bean Casserole
- Sour cream, milk and cream of mushroom soup. These both combine to make the ultimate creamy sauce for the chicken casserole.
- Chicken. Boneless skinless chicken breasts work great. Boneless skinless chicken thighs are another option. For either you choose, cut the chicken in small cubes so it cooks quickly.
- Green beans. I used canned green beans. If you have frozen or fresh green beans, cook them first before adding to the casserole.
- Seasonings. Salt, pepper, garlic powder and onion powder. Classic, comforting seasonings for a comforting green bean casserole with chicken.
- French fried onions. What’s a bean casserole without those crunchy onions on top?

How to Make Chicken and Green Bean Casserole
To prepare, preheat the oven to 375°F. Spray a 9×13-inch baking dish with cooking spray.
- Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Season the cubed chicken with salt and pepper. Cook the chicken for 6-8 minutes, stirring occasionally, until golden brown and fully cooked through. Drain any excess liquid and set aside.
- In a large bowl, mix together cream of mushroom soup, sour cream, and milk until smooth. Add garlic powder, onion powder, salt, and pepper to the mixture. Stir to combine.
- Fold in the diced chicken, drained green beans, and 1 cup of the shredded cheese.
- Transfer the green bean mixture to the prepared casserole dish. Sprinkle the remaining 1 cup of shredded cheese and french fried onions on the top of the casserole.
- Bake for 20 minutes until heated through.
Recipe Variations
- Use cream of chicken soup rather than mushroom soup if desired.
- Add stuff in! Try adding bacon, water chestnuts or diced mushrooms to the casserole, just like you would with traditional green bean casserole.
- Love rice? Add 1 ½ cups of cooked rice for a chicken and green bean casserole with rice.
- Swap out the chicken for leftover turkey during the holidays. It’s a great way to use up those leftovers.
- Use frozen or fresh green beans rather than canned if you prefer. Cook the green beans in simmering water for 5 minutes to soften them slightly.
What to Serve with Chicken Green Bean Casserole
Because this casserole has a creamy gravy, it’s perfect with a side of mashed potatoes and dinner rolls.
